RULES FOR SAFE OPERATION
To help ensure safe operation, please take a moment to learn the machine’s applications and limitations, as well as potential hazards. General® International disclaims any real or implied warranty and holds itself harmless for any injury that may result from improper use of its equipment.
-
Do not operate the drill press when tired, distracted, or under the effects of drugs, alcohol or any medication that impairs reflexes or alertness.
-
The working area should be well lit, clean and free of debris.
-
Keep children and visitors at a safe distance when the drill press is in operation; do not permit them to operate the drill press.
-
Childproof and tamper proof your shop and all machinery with locks, master electrical switches and switch keys, to prevent unauthorized or unsupervised use.
-
Stay alert! Give your work your undivided attention.
Even a momentary distraction can lead to serious injury. -
Fine particulate dust is a carcinogen that can be hazardous to health.
Work in a well-ventilated area and whenever possible use a dust collector and wear eye, ear and respiratory protection devices. -
Do not wear loose clothing, gloves, bracelets, necklaces or other jewelry while the drill press is in operation.
-
Be sure that adjusting wrenches, tools, drinks and other clutter are removed from the machine and/or the table surface before operating.
-
Keep hands well away from the bit and all moving parts. Use a hold-down or clamp to secure the stock, and use a brush, not hands, to clear away chips and dust.
-
Be sure that the bit is securely installed in the chuck before operation.
-
Be sure the bit has gained full operating speed before beginning to drill.
-
Always use a clean, properly sharpened bit. Dirty or dull bits are unsafe and can lead to accidents.
-
Use suitable work piece support if the work piece does not have a flat surface.
-
Do not push or force the bit into the stock. The drill will perform better and more safely when working at the rate feed for which it was designed.
-
Avoid working from awkward or off balance positions.
Do not overreach and keep both feet on floor. -
Keep guards in place and in working order. If a guard must be removed for maintenance or cleaning be sure it is properly re-attached before using the tool again.
-
Never leave the machine unattended while it is running or with the power on.
-
Use of parts and accessories NOT recommended by GENERAL® INTERNATIONAL may result in equipment malfunction or risk of injury.
-
Never stand on machinery. Serious injury could result if the tool is tipped over or if the bit is unintentionally contacted.
-
Always disconnect the tool from the power source before servicing or changing accessories such as bits, or before performing any maintenance, cleaning, or if the machine will be left unattended.
-
Make sure that the switch is in the “OFF” position before plugging in the power cord.
-
Make sure the tool is properly grounded. If equipped with a 3-prong plug, it should be used with a threepole receptacle.
Never remove the third prong. -
Do not use this drill press for other than its intended use. If used for other purposes, GENERAL® INTERNATIONAL disclaims any real implied warranty and holds itself harmless for any injury, which may result from that use.
